Could there be a better place for Hawaiian slack-key guitarist Patrick Landeza to celebrate the release of his new CD, "Ku'u Honua Mele" ("My Music World"), than Freight & Salvage? It's in his native Berkeley, where his Hawaii-born parents shared their spirit of aloha, and it's a showcase for technical mastery and world genres deeply rooted in tradition. With ukulele virtuoso Herb Ohta Jr. on hand, among other talented guests, to premiere the slack-key album flecked with Celtic, Latin and Western swing, Landeza should feel right at home. And so should the audience: "When you're at my show, you're sitting in my living room," he said. The musical parlor moves to Felton (near Santa Cruz) for a matinee Sunday.
